The effects of the Saccharomyces cerevisiae (SC) and Fructooligosaccharide (FOS) on body weight, feed conversion, body weight gain and immune response was investigated in broiler fed on aflatoxin (AF). A total number of 180 one day old broiler chickens (Hubbard classic) were randomly distributed into 6 experimental groups; G1: control (basal diet), G2: (basal diet + SC 2%), G3: (basal diet + FOS 0.25%), G4: (basal diet + AF100μg), G5: (basal diet + AF100μg + SC 2%), G6: (basal diet + AF100μg + FOS 0.25). The weight range, feed conversion, body weight gain and humoral immunity of birds were evaluated. Results of (G2) and (G3) show a significant (P<0.05) increase weight range, body weight gain, fed conversion ratio and the antibody titers in compare to control, while the AF contaminated diet (G4) showed decrease in body weight gain, feed conversion ratio and the antibody titers against Newcastle disease virus. Aflatoxin groups treated with 2% Saccharomyces cerevisiae (G5) and 0.25% fructooligosaccharide (G6) show increased in the broilers performance value and humoral immune response of broilers vaccinated against Newcastle virus disease as compared to the aflatoxin group (G4). In conclusion the addition of Saccharomyces cerevisiae and fructooligosaccharide had a beneficial effects on broilers health and can minimize the effect of aflatoxin on broiler performance and immunity.

Abstract
The study was conducted to detect Infectious Bronchitis Virus (IBV) in commercial chicken farms of Middle Euphrates, the technique have been used throughout the study protocol, Enzyme Linked Immunosorbent Assay (ELISA), Real Time Reverse Transcription Polymerase Chain Reaction (RT-PCR) and histopathological study. (172) serum samples were collected from clinically infected vaccinated broiler farm and (29) serum samples were collected from clinically infected non-vaccinated broiler farm, and screened for the presence of IBV antibodies by ELISA.75serum samples from 172 samples were positive ,(43.6%) distributed as followed 43 (61.4%) from Hella, 23 (36.5%) from Najaf and 9 (23.07%) from Diwaneyah ,29 serum samples collected from clinically infected non-vaccinated broiler flocks, were 5 (17.2%) serum positive samples for IBV. (75) tissue samples from clinically infected vaccinated broilers distributed were submitted for rRT-PCR technique, the results were as followed42 (56%) have been detected IBV, while 30 (71.4%) was positive in ELISA, and (15) samples from clinically infected non-vaccinated broilers showed 8 (53.3%) IBV were detectable while 5 (62.5%) was positive in ELISA. Also the research include study the histopathological changes of trachea, lung and kidney of infected birds which were positive for rRT-PCR.

The purpose of this study was to obtain additional information regarding
the effectiveness of Enrofloxacin (Baytril®) against artificially induced
infection of S. london in chickens.
One hundred and sixty one day old chicks of mixed sex were divided
equally into two groups A (treated group) and B (control, infected non-treated
group). Chicks were reared on separated rooms on wood shavings litter, and
given water and irradiated feed continuously for 55 days. All chickens were
infected at 3 days with 4×105 S. london/ml in drinking water. The administration
of salmonella was followed by intestinal colonization, detected by isolation of
salmonella from cloacal swabs, caecal contents and quantitative numeration per
grams of caecal contents, weekly for 8 weeks.
Group A was treated with Enrofloxacin (Baytril®) 0.5 ml/L drinking water
on day 45 for 5 days. Twelve days after the end of the therapy the presence of
salmonella could not be detected by cloacal swabs and in caecal contents.
This suggests that Baytril seems to have a good efficiency in total
elimination of salmonella from the intestine of infected chickens.

Abstract
The ability of dietary lactose and administration via drinking water to reduce Salmonella colonization of the crop and cecal contents of young chickens was evaluated.Chicks treatment consisted of dietary lactose treated group and administration lactose in drinking water treated group and control, in each group (150) chicks were placed. Chicks were challenged per os at 3 days of age with 106 cfu of Salmonella, bird samples were taken at day 7, 14, 21 and their crop and cecal contents were analyzed for Salmonella isolation rate from crop, number of Salmonella per gram from cecal content, and fecal shedding.The results showed that there is a total significant decrease in the isolation rate of Salmonella from crop and significant decrease in the number of Salmonella per gram of cecal contents and total significance decrease in the fecal shedding in the treated groups comparing to the control and there is no difference by using dietary lactose or administration via drinking water to reduce Salmonella colonization of broiler chicks and there is no divers effect on the body weight between all groups. (no significant difference).
